摘　　要：为了解决异构网络中的干扰问题,在介绍异构网络产生的背景、网络中节点类型及其特性的基础上,分析了应对层间干扰的各项技术,主要研究了增强型小区间干扰协调技术,并解析了几乎空白子帧的技术方案和低功率几乎空白子帧的实现方式。通过比较各种实施方案的优缺点,说明了低功率几乎空白子帧技术方案的灵活扩展性。In order to deal with the interference in heterogeneous networks,the technical background of heterogeneous networks,types and characteristics of network nodes were introduced.Then,different techniques to deal with the inter-layer interference were analyzed.Enhanced inter-cell interference coordination techniques were mainly investigated,including the implementations of ABS and LP-ABS.Advantages and disadvantages of different implementations were compared to validate the flexibility and expandability of LP-ABS.
